((CORROSION TESTINGS)) Common corrosion testings are Electrochemical Methods of Corrosion Testing (Electrochemical Polarization Experiment, No-Applied-Signal Tests, Small-Signal Polarization Tests, Large-Signal Polarization Tests, Scanning Electrode Techniques, …), Cabinet Testing (Salt fog, Neutral salt fog, Acetic-acid salt fog, Copper-accelerated acetic acid salt fog (CASS Test), Copper-accelerated acetic acid salt fog, Humidity fog, Corrodkote, Moist SO2, Acidified synthetic sea water (SWAAT test), Salt fog/SO2, Dilute electrolyte fog/dry, Scab corrosion creepback, Cyclic corrosion test, ), Microbiologically Influenced Corrosion Testing, Simulated Service Testing in the Atmosphere, Simulated Service Testing in Water, Simulated Service Testing in Soil, In-Service Techniques—Damage Detection and Monitoring, Electrochemical Techniques for In-Service Corrosion Monitoring, Slow strain rate test, … The very important point about corrosion testings is that most of them have been standardized by NACE and ASTM. This is because of law. ASTMs corrosion and wear standards provide the appropriate procedures for carrying out corrosion, wear, and abrasion tests on specified metallic materials and alloys. These tests are conducted to examine and evaluate the behavior, susceptibility, and extent of resistance of certain materials to stress corrosion cracking, cavitation erosion, intergranular corrosion, pitting and crevice corrosion, cyclic potentiodynamic polarization, exfoliation corrosion, atmospheric and galvanic corrosion, liquid impingement erosion, crevice repassivation, sliding and rolling friction, surface scratching and lubrication, cavitating liquid jet erosion, and hydrogen embrittlement. These corrosion and wear standards are useful to metallurgical companies, product manufacturers, and other users concerned with the specified materials in understanding the their wear and embrittlement behaviors.
